Initial reporter occupation: non-healthcare professional.Investigation: the reported allegations have been further investigated based on the information provided to date.The following allegations have been investigated: vena cava perforation, tilt.Filter interacts with ivc wall, e.G.Penetration/perforation/embedment.This may be either symptomatic or asymptomatic.Potential causes may include improper deployment; and (or) excessive force or manipulations near an in-situ filter (e.G., a surgical or endovascular procedure in the vicinity of a filter).Potential adverse events that may occur include, but are not limited to, the following: trauma to adjacent structures, vascular trauma, vena cava perforation, vena cava penetration.Filter tilt has been reported.Potential causes may include filter placement in ivcs with diameters larger than those specified in these instructions for use; improper deployment; manipulations near an implanted filter (e.G., a surgical or endovascular procedure in the vicinity of a filter); and (or) a failed retrieval attempt.Excessive filter tilt may contribute to difficult or failed retrieval; vena cava wall penetration/perforation; and (or) result in loss of filter efficiency.Potential adverse events that may occur include, but are not limited to, the following: unacceptable filter tilt.Catalog number is known; however, the lot number is unknown.The alleged tulip is manufactured and inspected according to specifications.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that the filter did not perform as intended, e.G.Intended for the prevention of recurrent pulmonary embolism (pe) via placement in the vena cava.Cook will reopen its investigation if further information is received warranting supplementation in accordance with 21 c.F.R.803.56.This report includes information known at this time.A follow-up medwatch report will be submitted if additional relevant information becomes available.

Event Description

The following information is alleged: the patient received a gunther tulip inferior vena cava (ivc) filter on (b)(6) 2009.Approximately 9 years and 1 month later, the patient underwent a computed tomography (ct) scan which revealed that the anterior filter strut was seen piercing the antero-medial wall of the inferior vena cava by 10.93 mm; that the postero medial filter strut was seen piercing the corresponding wall of the inferior vena cava by 13.06 mm and was seen lying adjacent to the prevertebral structures; that the postero-lateral filter strut was piercing the posterolateral wall by 9.0 mm; and that there was a 27.36 degree anterior tilt of the ivc filter.Approximately 7 months later the patient consulted a doctor regarding the removal of the ivc filter.The doctor revealed that the risk of removing the filter were much higher than leaving the filter in.Approximately 1 year and 5 months later the patient underwent another ct scan of the chest, abdomen and pelvis.The radiology report revealed that most inferior aspect of the filter was projecting towards the head to the right renal vein.Hospital and medical records have been requested, but not yet provided.

Event Description

Patient allegedly received an implant on (b)(6) 2009 via the right internal jugular vein due to significant thrombus present within the ivc extending above the level of renal veins.The patient alleges tilt, vena cava perforation and unable to remove.The patient further alleges a few of the filter legs are piercing through the ivc, one strut is lying adjacent to the prevertebral structures", anxiety, limited mobility, and post implant deep vein thrombosis (dvt).(b)(6) 2020, per a report from computed tomography; ¿stable appearance of the ivc filter, with the most inferior aspect of the filter projecting 3.2 cm cephalad to the right renal vein.¿.

Blank fields on this form indicate the information is unknown, unavailable, or unchanged.The following fields were updated per additional information received: a2, a4, b1, b2, b5, b6, b7, annex e, annex a, annex b, annex c, annex d, and h6.Investigation the following allegations have been investigated: deep vein thrombosis (dvt), unable to remove, anxiety, limited mobility.Investigation is reopened due to additional information provided.The reported allegations have been further investigated based on the information provided to date.Ivc occlusion/ thrombosis, new dvt, ivc stenosis as a reported complication, is a known risk in relation to filter implant and is well documented in the clinical literature and in clinical practice guidelines.This is supported by the clinical evidence report established to assess available clinical data to identify and evaluate the clinical safety and performance of the cook vena cava filters.Potential adverse events that may occur include, but are not limited to, the following: vena cava occlusion or thrombosis, vena cava stenosis, deep vein thrombosis.Physician practice guidelines and published guidance from regulatory agencies recommend that patients with indwelling filters undergo routine follow-up.The risks/benefits of filter retrieval should be considered for each patient during follow-up.Once protection from pe is no longer necessary, filter retrieval should be considered.Filter retrieval should be attempted when feasible and clinically indicated.Filter retrieval is a patient-specific, clinically complex decision; the decision to remove a filter should be based on each patient¿s individual risk/benefit profile (e.G., a patient¿s continued need for protection from pe compared to their experience with and (or) ongoing risk of experiencing filter-related complications).For all retrievable ivc filters, retrieval becomes more challenging with time, and this is commonly due to encapsulation of the filter legs or hook (in a tilted filter) by tissue ingrowth.The filter is designed to be retrieved with the günther tulip vena cava filter retrieval set.It may also be retrieved with the cloversnare® vascular retriever.Cook has not performed testing to evaluate the safety or effectiveness of filter retrieval using other retrieval systems or techniques.The published clinical literature includes descriptions of alternative techniques for filter retrieval; use of these techniques varies according to physician experience, patient anatomy, and filter position.The safety or effectiveness of these alternative retrieval techniques has not been established.Specific for ¿embedded¿ a filter that is embedded in the wall of the ivc may be difficult to retrieve.For all retrievable ivc filters, retrieval becomes more challenging with time, and this is commonly due to encapsulation of the filter legs or hook (in a tilted filter) by tissue ingrowth.Unknown if the reported anxiety and limited mobility are directly related to the filter and unable to identify a corresponding failure mode at this point in time.Catalog number is known.Lot number is unknown; however, the alleged tulip is manufactured and inspected according controls.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that the filter did not perform as intended, e.G.Intended for the prevention of recurrent pulmonary embolism (pe) via placement in the vena cava.Cook will reopen its investigation if further information is received warranting supplementation in accordance with 21 c.F.R.803.56.This report includes information known at this time.A follow-up medwatch report will be submitted if additional relevant information becomes available.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, or that any cook device caused or contributed to or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
